org.apache.http.TruncatedChunkException: Truncated chunk
項目中使用請求遠程接口報錯 ，項目是Spring-boot的，兩個項目（A和B） , A調用B的rest接口，返回json數據，A系統報錯以下異常，B系統沒有報錯。
記錄一下處理方式，方便再次遇到這個問題的人java

當系統報以上錯誤時，接口表現出來的是數據傳輸不完整， 好比說接口返回 json ， 那麼接收到的數據可能會少一截，json 數聽說不定會少個 ｝ ，此時json就沒法反序列化了。說白了就是丟包了。nginx
經過大半天的查找，終於定位到是nginx的問題，由於nginx處理chunked傳輸有問題。
因此最簡單的處理方式是把nginx的緩存關閉。apache
